Release Notes: Nping packet probing and analysis tool has been added. Nmap Scripting Engine has been enhanced, and many new NSE scripts and libraries have been added (the new totals are 177 and 54, respectively). Many OS fingerprints and version detection signatures have been added, bringing the totals to 2,982 and 7,319, respectively. Zenmap GUI has been made faster when handling giant enterprise networks, and some new features have been added to it (script selection interface, printing support, and more).
Release Notes: 320 important changes were made, including the Zenmap cross-platform GUI, a 2nd generation OS detection system, the Nmap Scripting Engine, a rewritten host discovery system, performance optimizations, advanced traceroute functionality, TCP and IP options support, and nearly 1500 new version detection signatures. It is recommended that all current users upgrade.
Release Notes: This stable release incorporates many improvements from 13 development releases over the last 6 months. These include a second generation OS detection system that is faster and more accurate, support for IP options (source routing, record route, etc.), an --open option for showing only open ports, version detection database updates, more detailed XML output, and dozens of bugfixes.
Release Notes: This release includes dozens of more detailed SSH version detection signatures. It also detects the Nessus daemon. Several bugs were fixed, including Solaris and HP-UX compilation problems.
Release Notes: This release is a grab bag of new features and bugfixes. 300 signatures were added to the version detection database, bringing the total up to 3,441 (representing 401 protocols). Output was streamlined to allow multiple ignored port states so your console isn't flooded when a host has thousands of ports in both the filtered and closed states. ICMP rate limiting detection was optimized for faster scanning. There were also dozens of other bugfixes and minor feature additions.
Release Notes: This release fixes reverse-DNS bugs that affected it when running on big-endian machines or Windows, and also fixes a rare crash bug. It includes the maximum segment size (MSS) option in TCP packets to be less conspicuous. DragonFly BSD is supported.
Release Notes: This release includes a rewritten (for speed and memory efficiency) port scanning engine, ARP scanning, a new man page, runtime interaction, 'l335 ASCII art, massive version detection improvements, MAC address spoofing, increased Windows performance, 500 new OS detection fingerprints, completion time estimates, a GTK2 frontend, parallel DNS resolution, options for sending bad checksums and limiting retransmissions, source port zero scans, an XSL stylesheet for producing HTML reports, and much more.
Release Notes: This is a pre-release for testing before the upcoming 4.0 release. Changes since version 3.99 include runtime interaction support for Windows (it already worked on UNIX), new nmap-mac-prefixis and nmap-protocols files, an updated (to 6.4) LibPCRE, and some fixes to enable compilation on the new Intel-based Macs.
Release Notes: The new runtime interaction system provides time estimates and verbosity/debugging setting changes at the tap of a key while Nmap executes. Reverse DNS resolution has been parallelized with custom code to speed up large scans. The new --max-retries option can also improve performance. The version detection DB has been updated to 3,153 signatures for 381 different service protocols. The --badsum option helps you detect tricky firewall/IDS systems. Dozens of fixes and smaller features have also been added.
